    Finally upgraded my smart phone from an old htc to a Moto G6. The technician was excellent and helped me get the new phone set up. Answered all my questions and was very friendly, patient, knowledgeable, and efficient. The phone has more power and ability then I need now, but as the kids teach me how to use it, I can expand my abilities easily.

    At first it was a little hard to use but after a few you tube videos the calculator is paying off big time. Makes graphing functions and finding derivatives easy.
